Installation
Relieve all pressure from the actuator.
Loosen travel stop nuts on Travel Stops B.
Ensure actuator lockout (if provided) is disengaged.
Unthread Travel Stops B-1 and B-2 four to five full turns each.*
Adjust both B-1 travel stops until they contact the clevis simultaneously. It will
be necessary to apply pressure to P1 and P2 between adjustments to determine
the final position of travel.
With pressure to P1 and P2, thread in Travel Stops B-2 until they are in firm
contact with the clevis.
With pressure still to P1 and P2 ensure that all Travel Stops B are in firm contact
with the clevis and tighten all travel stop nuts until they are in contact with the
body, then tighten an additional 1/4 turn.
